Supernova Theory Exploded

What happens when two white dwarf stars in close orbit finally fall into one another? Theory says you get a colossal explosion called a Type-I supernova. But this hypothesis is in trouble because a recent survey of white dwarfs revealed absolutely no double white dwarfs in a sampe of 25 from the Milky Way. Even if a few pairs are eventually found, they do not appear to be numerous enough to account for the rate at which supernovas are observed.
